s claims.

Our invention relates to a composite structure and, in particular, to a structure having a support of relatively cheap material such as cold rolled steel, and a decorative structure consisting of a combination of stainless'steel or the like and a plastic material or the like.

It .is the object of our invention to provide decorative moldings or panels having alternative areas of one material, such as a plastic matelo rial or'the like, which may be of varying colors with borders of stainless* steel or other contrasting material to furnish the'desired contrasting n decorative eiect; and, at the same time, to provide a structural support of` adequate strength la and of cheaper material so as to provide the necessary rigidity for the structure comprising the contrasting material, which support is concealed from the eye of the observer. Due to the high cost of stainless steel, the expense of a im molding made entirely of this material is prohibitive. If this material is used entirely for decorative purposes, it is impossible to achieve designs and contrasting color arrangements to relieve the monotony of the molding so formed.

We have produced a structure wherein the utmost decorative effect of contrasting materials is` utilized and wherein the main body of the molding which supportsborders of stainless steel or the `like is of a relatively cheap. plastic mal terial or the like, such as, for instance, celluloid", which is supported by a supporting member of relatively cheap cold rolled steel or the like, to which 'the celluloidv or plastic material is preferably integrally'attached. 'l

It is the object of our invention to provide a rigidly supported composite structure of plastic material having contrasting lborders of stainless steel, which plastic material, in addition to forming, with the contrasting stainless steel borders,

40 a pleasing contrasting effect, also provides support for the stainless steel borders.

This application is a division of our copending application Serial No. 33,860 filed July 30, 1935.

Referring to the drawing: V

'Figure 1 is a top plan view of the composite molding comprising a strip of plastic material bordered by engaging stainless steel strips and supported by a coldrolled steel support which is directly attached to the back of the strip of plastic material;

Figure 2 is an end elevational view of the structure shown in Figure l. 1

When referring to such materials as stainless steel, "celluloid and cold rolled steel, it

materials generically and by way of illustration only, and do not desire to conilne ourselves to these particular materials but only to those of the same general characteristics, advantages and disadvantages.

Referring to the drawing in detail, i designatesfthe vertical portion of a cold rolled steel support having an attaching flange 2. The attaching ilange is preferably integral with the-l body of the support and preferably comprises a struck-up portion disposed at an angle to the vertical portion of thesupport. These anges preferably comprise separate struck-up' portions which are spaced from one another throughoutl the length of the support. Formed integrally withl this cold rolled steel support is a horizontally disposed portion extending at right angles to the portion i, and designated 3. `'I'his portion 3 has an attaching face, upon which the strip, plate or sheet 4 of plastic material, such as ce1- luloid or the like, is secured.

As shown in Figure 2, the portion 3 of the support has a perforation 6 therein for the purpose of receiving the portion 5 of the plate, strip or sheetl, which portion 5 is preferably extruded under vheat or pressure to attach the -plate 4 to the attaching face of the portion 3 ofthe support l. Stainless steel edge-engag-v ing strips 1 are employed .to add the necessary decorative eiect. f

It will be understood that the foregoing description is illustrative and inno wise limitingl and that we desire to comprehend within our invention such modifications as may be necessary to adapt it to varying conditions and uses.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is:

1. In combination, an angular backing plate,

a plastic plate attached to one face thereof, and

stainless steel edging strips turned over and enclosing the edges of said plastic plate at opposite sides of said backing plate.

2; A molding structure comprising a cold rolled `steel angle support member having a strip of plastic material rigidly attached thereto, and a pair of edge-engaging strips of stainless steel secured to said strip ofY plastic material out of v .attaching iiange integral therewith. said sup- A i'port member having a strip of celluloid rigid- 'ly attached to one face thereof, and `s. pair of 10 edge-engaging strips of stainless` steel-secured to and supported solely by said' strip ot celluloid."

.5. In combination, an angular backing plate of cold rolled steel having a celluloid plate attached to one face thereof, said "celluloidf plate Yhaving stainless steel edging strips turned over its edges with the side edges thereof spaced from one another on oneside of said Celluloid plate, whereby to expose a portion of the cel1u1oid" plate therebetween.
